Abstract: PURPOSE:To confirm the outline of contents before photographic printing by providing a processing circuit, etc., for converting an input color signal to a monochromatic signal without providing a screen memory such as a field memory, and also providing a function for selecting a photographic printing state in hard copy processing on the monochromatic of a monitor. CONSTITUTION:A monochromatic formation part 4 generates the monochromatic signal by the analog addition of input signals R, G, and B and inputs it to a switch 5, which selects a signal corresponding to the photographic printing. An A/D converter 6 performs digital conversion for the photographic printing and the clock for sampling at this time is generated by a clock generating circuit 14. When the clock is generated, the conditions of the frequency, phase, etc., are indicated with an external input 10. Namely, the switch 5 selects a monochromatic mode at the time of this setting and the state set with the external input 10 passes through switches 11-13 and displayed on the monitor on a monochromatic basis, so that the conditions are set again over a look at the state. Consequently, a memory for the whole screen is not provided in the device and the outline of a photographic printing result can be viewed before the photographic printing with a small number of components.

Filed: 1987-04-21
Abstract: PURPOSE:To accurately detect the position of a moving vehicle to a frame even in case of no difference between light reflectivities of a ceiling face and the frame by extracting break parts of two slit beams orthogonal to each other and obtaining the position of the moving vehicle to these extracted parts. CONSTITUTION:Two slit beams B1 and B2 orthogonal to each other are projected toward the ceiling so that the intersection is off the intersection position of the frame, and images of slit beam projected positions of the frame are picked up in directions different from projection direction of both slit beams B1 and B2, and then, slit beams look broken in positions Ba and Bb where both slit beams traverse the frame because the frame is protruded downward from the ceiling face. Positions Ba and Bb where both slit beams B1 and B2 look broken are changed in accordance with the change of the position of the moving vehicle to the frame. Consequently, parts Ba and Bb where both slit beams B1 and B2 are broken are extracted from picked-up information of an image pickup means and the position of the moving vehicle to the frame is obtained from position information of extracted parts.

Abstract: PURPOSE:To ensure the error checking with high reliability, by providing plural data error detecting means which convert data from a series form into a parallel form to detect a data conversion error of an odd number of bits as well as to perform the block checking of the series data. CONSTITUTION:A series data given through a reception data line 102 is received 201 and converted into a parallel data.

When the text is totally received, the circuits 202 and 203 work continuously until they finish to receive check characters and deliver the results of reception of check characters to circuits 105 and 106. At the same time, the vertical parity check result obtained from a series data receiving circuit 201 is delivered to a circuit 104. The outputs of circuits 104-106 are stored in a register 301 to decide the quality of these circuits. When the quality of circuit is not good, the retransmission of data is requested. Then the data is fed to a lower order only when the quality of circuit is decided good. This improves the reliability for error checking.

Title: Exposure data generating method
Inventor: MANABE YASUO
IPC: G03F1/70
Filed: 1989-04-18
Abstract: PURPOSE:To restrain chip exposure data from increasing in processing time and to improve it in interchangeability when a part of a functional block is replaced by a method wherein a data extraction region is provided around the exposure data of the functional blocks laid out, and the data extracted by the data extracting region is used as a reference data for the correction of a proximity effect. CONSTITUTION:When a functional block 3 is modified or replaced, a part of data stored in functional blocks 1, 2, 4, 7, 8, 10 and 11 provided adjacent to the functional block 3 is extracted by a data extracting region 3a, and the correction of a proximity effect is made to the pattern data of the peripheral part of the functional block 3 using the extracted data. Therefore, the object can be met by correcting only the data of the functional block 3, so that the light exposure data of the whole chip is not required to be reconstructed and consequently a data processing time can be restrained from increasing. The sub-fields of functional blocks may as well be different from each other in size and the functional blocks are improved interchangeability with other blocks of different sizes.
